SOEKAVIA 1.5V AAA Battery Rechargeable Lithium 400mAh, USB Charged, Overcharge Protection, with USB Cable /4Pcs

Happy with purchaseUsed for an electric toothbrush. Alkaline AAAs slowed down fairly quickly so we either had a slow toothbrush for a long time or ate through disposables. Normal 1.2v rechargables were slow from the start.The cut off is sudden so it's useful to have spares ready to go when it dies halfway through brushing. Lasting a week and a half between charges so farNote: only recharged twice so no idea of longevity

I use these in my Bose QC headphones when travelling. Love the simplicity of being able to charge them up from my phone charger with the mini USB provided. Elegant lightweight compact solution for AAA run devices.

These dont work in the cree type torches, beware !!, they do work if you have a standard bulb though (not sure why).

Brilliant, proper 1.5 volts, recharge quickly, discharge at 1.5v until dead
